cannot refactor (introducing a new method parameter) [message #502627]

Hi all,
I've got a project under a git repository and I was trying to do a simple code refactoring: introducing a new parameter into a method of an abstract class with a few implementations in subclasses. The project, of course, was compiling fine (no errors) before the refactoring. However, I was unable to perform the refactoring and I received a "Class file name must end with .class" error. Having a look at the log I found the following:

Anybody has an idea of what the problem could be? One year ago I found a refactoring problem due to the use of SVN, could it be something similar? Please note that the code was in committed state.

Thanks

Thanks, Dani!
I should have checked bugzilla first..
So.. we should wait for the next release, basically, I understand? Ok, it's a bit annoying but i can live with it..

Or you use a 3.6 build, e.g. I20100217-0800.

Not always perfect, since it is an integration build. But I work on
those daily. If you want to be safer you can wait for M6, which will be
the next "stable" build.
